Access control method and device

Abstract

An access control method, including obtaining, by a protocol-stack upper layer of a terminal, an override identifier, starting, by the protocol-stack upper layer of the terminal, an application specific congestion control for data connectivity (ACDC) check according to a service initiated by the terminal, and, if the protocol-stack upper layer of the terminal confirms that the service initiated by the terminal can pass the ACDC check and determines that the override identifier corresponding to an application identifier of the service passing the ACDC check is overriding an access class barring (ACB) check, sending, by the protocol-stack upper layer of the terminal, an radio resource control (RRC) establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check.

What is claimed is: 
     
       1. An access control method, comprising:
 obtaining, by a terminal, an override identifier; 
 determining, by the terminal, whether the override identifier is overriding an access class barring (ACB) check after a service initiated by the terminal passes an application specific congestion control for data connectivity (ACDC) check; 
 establishing, by the terminal, a radio resource control (RRC) connection in response to the terminal determining that the identifier is overriding the ACB check; and 
 starting, by the terminal, the ACB check in response to the terminal determining that the coverage identifier is not overriding the ACB check, and establishing, by the terminal, the RRC connection after the ACB check is passed. 
 
     
     
       2. The method according to  claim 1 , wherein the obtaining the override identifier, comprises:
 receiving, by the terminal, a system broadcast message from a wireless access network device, wherein the system broadcast message comprises the override identifier. 
 
     
     
       3. The method according to  claim 2 , wherein the system broadcast message further comprises a service list. 
     
     
       4. The method according to  claim 1 , wherein the terminal is in idle state. 
     
     
       5. An apparatus, comprising:
 a processor; and 
 a computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
 obtain an override identifier; 
 determine whether the override identifier is overriding an access class barring (ACB) check after a service passes an application specific congestion control for data connectivity (ACDC) check; 
 establish a radio resource control (RRC) connection if the identifier is overriding the ACB check; and 
 start the ACB check if the coverage identifier is not overriding the ACB check, and establish the RRC connection after the ACB check is passed. 
 
 
     
     
       6. The apparatus according to  claim 5 , wherein the apparatus further comprises a receiver,
 wherein the program further includes instructions to utilize the receiver to receive a system broadcast message from a wireless access network device, wherein the system broadcast message comprises the override identifier. 
 
     
     
       7. The apparatus according to  claim 6 , wherein the system broadcast message further comprises a service list. 
     
     
       8. A non-transitory computer-readable storage medium storing a program to be executed by a processor, the program including instructions for:
 obtaining an override identifier; 
 determining whether the override identifier is overriding an access class barring (ACB) check after a service passes an application specific congestion control for data connectivity (ACDC) check; 
 establishing a radio resource control (RRC) connection if the identifier is overriding the ACB check; and 
 starting the ACB check if the coverage identifier is not overriding the ACB check, and establishing the RRC connection after the ACB check is passed. 
 
     
     
       9. The non-transitory computer-readable storage medium according to  claim 8 , wherein the instructions for obtaining an override identifier comprises instructions for:
 obtaining a system broadcast message, wherein the system broadcast message comprises the override identifier.
